  • This study was conducted to evaluate the growth of lactic acid bacteria and quality characteristics of Baechu kimchi prepared with four types of salt (Solar salt, Flower salt, Hanju salt, and Roasted salt) at two different concentrations (10, 15%) during storage. The quality characteristics of kimchi were examined by investigating acid production, growth of lactic acid bacteria, sensory properties, salinity, texture, and color characteristics. Baechu kimchi was fermented for 18 days at $10^{\circ}C$. The pH and total acidity did not change during storage according to type and concentration of salt. Growth of lactic acid bacteria was not affected by type of salt, whereas it was inhibited at 15% salt concentration after 9 days of fermentation. In the quantitative descriptive analysis of sensory properties, kimchi prepared with 10% salt showed significantly higher scores in term of overall acceptability (p<0.05). Meanwhile, there was no significant difference by type of salt. For texture characteristics, hardness of kimchi prepared with 10% salt was significantly higher than that with 20% salt. For color characteristics, L value (brightness) and b values (yellowness) of kimchi prepared with 10% salt increased during fermentation, whereas a value (redness) did not change by type and concentration of salt. The results of this study show that there were no considerable differences in quality characteristics of Baechu kimchi prepared with various types and concentrations of salt. However, Solar salt resulted in more favorable sensory properties and salinity of kimchi than any other types. Further, kimchi prepared with 10% salt showed significantly higher scores in terms of overall acceptability, growth of lactic acid bacteria, salinity, texture, and color characteristics.

  • To determine the kimchi with the best quality and functional characteristics, we manufactured and compared recipes for Korean and Japanese kimchi made either Korean or Japanese baechu cabbages. All batches were fermented for 4 weeks at $5^{\circ}C$, and tested for pH, texture, microbial count, sensory evaluation, DPPH radical-scavenging activity, and cell proliferation (using the MTT assay on AGS human gastric cancer cells). By the third week of fermentation, Korean kimchi made with Korean baechu (KK) and Japanese kimchi made with Korean baechu (KJ) showed a higher acidity than Korean or Japanese kimchi made with Japanese baechu (JK and JJ, respectively). KK ranked highest in springiness, followed by KJ, JK, and JJ. Therefore, the texture of kimchi produced with Korean baechu was appears better than kimchi produced with Japanese baechu. This was confirmed in masticatory tests. Kimchi produced with Korean baechu (KK and KJ) showed lower total aerobic bacterial counts, while the total lactic acid bacterial counts were higher (p<0.05). In sensory evaluation test, KK received the highest overall acceptability score, while JJ earned the lowest score. In the DPPH assay for anti-oxidative activity, KK showed a 94% anti-oxidative effect, followed by KJ (92%), JK (91%), and JJ (88%) (p<0.05). In the MTT assay for analyzing the cell proliferation of AGS human gastric cancer cells, KK showed a 64% anticancer effect in vitro, followed by KJ (57%), JK (38%), and JJ (26%). Therefore, the anti-oxidative and anti-cancer functionalities of kimchi made with Korean baechu were higher than those made with Japanese baechu, regardless of the kimchi recipe applied. Overall, Korean baechu had important and superior effects on the quality and functionality of kimchi.

  • Nitrate contents and quality characteristics of Ulgari-Baechu Kimchi, Yulmoo Kimchi, and Yulmoo Mul-Kimchi were investigated during a storage period. In case of Ulgari-Baechu Kimchi and Yulmoo Kimchi, an increase of pH and decrease of acidity were distinguished by the 4th day of the storage after fermentation. In Yulmoo Mul-Kimchi, pH value decreased and total acidity increased through the whole storage period. Total microbial and lactic acid bacterial counts of Yulmoo Kimchi and Ulgari-Baechu Kimchi reached the peak at the 4th day of storage and slowly decreased after the 18th day. Total microbial and lactic acid bacterial counts of Yulmoo Mul-Kimchi were also the highest at the 4th day of fermentation but showed gradual decreases from the same day. Nitrate contents of Ulgari-Baechu Kimchi significantly decreased by fermentation at room temperature, which continued during the whole store period to down by 11%. Showing the similar pattern in the nitrate content change, Yulmoo Kimchi and Yulmoo Mul-Kimchi recorded 12% and 5% decrease, respectively.

  • Physicochemical properties of commercial long-term fermented kimchies which are widely available in Korea were investigated. The commercial long-term fermented kimchies were fermented almost more than 6 months. Average values for saltiness, pH and acidity of the long-term fermented kimchies were $3.0{\pm}0.5%$, $4.0{\pm}0.2$, and $1.88{\pm}0.76%$, respectively. The long-term fermented kimchi showed similar Leuconostoc sp. and Lactobacillus sp. counts as baechu kimchi ripened properly during fermentation. The amount of Leuconostoc sp. and Lactobacillus sp. of the long-term fermented kimchi were $10^{7\sim8}$ CFU/mL and $10^{4\sim7}$ CFU/mL, respectively. The long-term fermented kimchi showed $0.32{\pm}0.18$ lightness, $1.73{\pm}0.98$ redness, $0.52{\pm}0.31$ yellowness. Long-term fermented kimchi showed higher lightness, redness, yellowness than well-fermented standardized baechu kimchi. Breaking strength of long-term fermented kimchi was higher than that of well-fermented standard baechu kimchi.

  • This study was conducted to examine morphological characteristics and the content of cell wall polysaccharides of Brassica campestris var. pekinensis(baechu). First of all, the variety of scientific name and naming of parts of baechu in the literatures of kimchi showed, which will unify marks. So, we propose not so much mid-rib and leaf blade of baechu leaf as white part and green part, respectively. On the other hand, the forms of vessel elements of white part in baechu consist in ring, sclariform and reticulate thickening. The proximate compositions and contents of cell wall polysaccharides of baechu has significant differences between its cultivars. The cell wall pectin from baechu exhibited four peals with molecular weights of 2,000,000, about 100,000 and less than 10,000 by gel filteration chromatography and hemicellulose did two peaks with molecular weights of 2,000,000 and 10,000.

  • This study was conducted to investigate sorbitol utilization of Lactobacillus species isolated from Kimchi and the effects of sugar, starch syrup and sorbitol on the pH, titratable acidity, microorganism and sensory evaluation of baechu Kimchi during fermentation at $10^{\circ}C$. Three species among ten Lactobacillus species isolated from Kimchi could not utilized medium with sorbitol. The pH of baechu Kimchi with addition of 1% sugar sources and sorbitol were similar to pH of control baechu Kimchi, while the titratable acidity were different between samples. The titratable acidity of baechu Kimchi with addition of sugar sources was higher than control. Increasing in sorbitol addition, the titratable acidity of haechu Kimchi was more remarkable lower than control during fermentation proceeded. The total number of viable cells and Lactic acid bacteria were not significantly difference among those of Kimchi samples. In the chewiness of textural properties, baechu Kimchi with addition sorbitol showed higher score than control. However, Kimchi samples prepared with 1% sugar sources were not significantly differences in sensory properties, while the Kimchi samples with 5, 10% sorbitol were higher score than control in the overall acceptability and texture.

  • This study was carried out to determine the physicochemical, microbiological, and quality characteristics of a new type of fermented sausage manufactured by incorporating Baechu-kimchi powder and gamma-aminobutyric acid (GABA)-producing lactic acid bacteria (LAB). The LAB count was at the maximum level by day nine of ripening in inoculated sausages, accompanied by a rapid decrease in the pH. The addition of kimchi powder decreased the lightness ($L^*$) and increased the redness ($a^*$) and, yellowness ($b^*$) values, while also significantly increasing the hardness and chewiness of the sausage (p<0.05). Moreover, although the thiobarbituric acid reactive substances values increased in all samples during the study period, this increase was lower in the kimchi-treated samples, indicating a reduction in lipid oxidation. Overall, our results show that the addition of Baechu-kimchi powder to sausages reduced the off-flavor properties and improved the taste profile of the fermented sausage in sensory evaluations. The GABA content of all fermented sausages increased from 17.42-25.14 mg/kg on the third day of fermentation to 60.95-61.47 mg/kg on the thirtieth day. These results demonstrate that Baechu-kimchi powder and GABA-producing LAB could be functional materials in fermented sausage to improve quality characteristics.

  • Purpose: The purpose of this study is to analyze nutrient intake and frequently consumed foods according to the intake frequency of Baechu (Chinese cabbage) kimchi by Korean adults. Methods: Data from analysis of 7,122 subjects aged 19~64 years from 2012, 2013 KNHANES were obtained from health behavior interviews and the 24-hour dietary recall method. Results: With the daily intake frequency of Baechu kimchi, subjects with two times a day were the highest proportion among total subjects. As Baechu kimchi intake frequency of breakfast, lunch, and dinner increased, the rate of skipping meals decreased significantly (p < 0.05). In addition, all food intake and daily nutrient intake increased significantly with increasing frequency of daily Baechu kimchi intake (Crude p for trend < 0.05, Adjusted p for trend < 0.05). With the frequently consumed foods by daily Baechu kimchi intake frequency in 2012 and 2013, among 509 foods top ranked foods were white rice, Baechu kimchi, beer, distilled alcoholic drink, milk, and pork. Conclusion: The results of this study could be used in the future to promote consumption of kimchi in the Korean population.

  • This study was carried out to investigate the effectiveness of Leuconostoc mesenteroides isolated from octopus baechu kimchi as a potential starter for seafood kimchi. L. mesenteroides is lactic acid bacterium currently used as a starter for kimchi production. We selected the most effective L. mesenteroides strain from the 7 strains isolated from octopus baechu kimchi and, based on biochemical properties and 16S rRNA sequencing, identified the selected strain as L. mesenteroides SK-1. The SK-1 strain exhibited acid-tolerance, good survival capacity, and excellent dextran productivity. We investigated the effects the SK-1 of starter on seafood kimchi fermentation. Octopus baechu kimchi was fermented with L. mesenteroides SK-1 at $4^{\circ}C$ for 35 d. The decrease in pH and increase in acidity in octopus baechu kimchi fermented with the SK-1 starter occurred more quickly than that in the control kimchi indicating that. Octopus baechu kimchi with SK-1 starter has a relatively slow rate of increase in lactic acid production. As a result, octopus baechu kimchi prepared with L. mesenteroides SK-1 can be maintained at a suitable ripening degree over an extended period of time compared to that of the control kimchi, Moreover, the octopus baechu kimchi started with L. mesenteroides SK-1 has excellent sensory properties, including a refreshing taste, and a weak sour odor.

  • This study was carried out to investigate the intake pattern and the experience on the kimchi-making, and to analyze the taste preference of kimchi. The questionnaires have been collected from 473 college students in Taejon. Most students had taken baechu-kimchi, kkakduki, yeolmu-kimchi, dongchimi, and cheonggak-kimchi. They liked baechu-kimchi best, and then cheonggak-kimchi. Twenty-seven percent of students took kimchi every meal time and 53 % once a day. The rest 19.4% replied that they could take meals without kimchi. The male students ate more kimchi than the female(p<0.01). Sixty-five percent of them had tried the foreign foods made with kimchi and female had more experience than male(p<0.01). The taste of kimchi-japchae and kimchi-woodong was indicated as edible or taste very good by over two thirds of the students. Kimchi-pizza, kimchi-hamburger, and kimchi-spaghetti were evaluated as edible or taste good by the over half. The aging of kimchi was believed to be the most important factor to determine the taste. Students preferred kimchi which was weak in salty, sweet, and jot-kal taste, strong in hot taste, and proper in sour taste(well-fermented). Compared with the male, the female enjoyed kimchi having stronger sour and weaker jot-kal taste(p<0.01). More female students(43.5%) had experenced kimchi-making than the male(26.5%)(p<0.001). Three-fourth of them had made kimchi with their mother. Baechu-kimchi, cheonggak-kimchi, and dongchimi were recommended as the global food.
